Research on an Adaptive Sleep Algorithm for Wireless Sensor Networks

降低无线传感器网络的能耗一直是迫切解决的问题。通过对无线传感器网络节点能耗分布情况的研究,发现对无线传感器网络节点休眠,可以减少节点收发能耗。针对降低无线传感器网络节点能耗的问题,文中基于多因素、多层次的层次分析法,设计了一种无线传感器网络自适应休眠算法(AHP休眠算法)。实验表明该算法依据信息采集需求和节点剩余能量自适应控制网络节点的休眠和收发,与传统的RS休眠和定时休眠算法对比,提高了节点能量的利用率,延长网络生命期。

To reduce the energy consumption for WSN is always the problem to be solved. Through research on the energy comsumption distribution of node for WSN, discover that making the nodes of WSN sleeped can decrease the energy consumption. As for the question of reducing the energy consumption of WSN node,had constructed an adaptive sleep algorithm for WSN （ AHP sleep algorithm） which had been based on the Analytic Hierarchy Process of multi-factor,multi-level hierarchy. The experiments showed that this algorithm could adaptively control network nodes in sleep or transceiver. The algorithm also could improve node energy utilization and extend the network lifetime after compared with the traditional RS sleep and timing sleep algorithm.
